No or yes. Depends on how much you want to tell your daughter.
I have those books. The series is good. My daughter likes it. She is 9.
5th Grade. But I got her those books from when she was younger. And good grief, my Husband... even talked to my daughter about periods. But well, at least he is being a participatory Dad and is open with his daughter. And my daughter had no problem with it.
It is really up to you and a personal thing to decide, for your girl.
The books do have an age range, I forget what it was. Just look it up online. I think it says 8+ years old.
My daughter was using deodorant from an earlier age. Like 7. No biggie. She knew how to use it, she sees me doing it. She just puts it on in the morning before she gets dressed. Just like brushing her teeth.
I got her the Arm & Hammer "Essentials Natural" Deodorant. It has no aluminum or parabens in it.
And from 3rd grade, my daughter's Teachers would talk to the class about using deodorant because, kids were getting smelly at school.
Some girls, get their periods from 9 years old.
And they at that age, start to develop breasts too. I have seen that in my daughter's classmates.
Even the Teachers told me... from 9 years old... their body starts to change for some girls.
